Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning fans, and particularly to an air-conditioning fan that prevents water ingress. Background Art

[0002] An air-conditioning fan mainly consists of components such as a motor, an impeller, and a fan housing. The motor drives the impeller to rotate. During the rotation of the impeller, centrifugal force is generated, causing air to be sucked into the fan housing and discharged along the tangent direction of the impeller, thereby realizing the flow and transportation of air. It can be applied to air conditioning, air humidification, and ventilation operations. In an air-conditioning system, the air-conditioning fan promotes the continuous circulation of indoor air.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting the baffle frame and opening and closing the front sealing plate, the upper sealing plate and the lower sealing plate, when the air-conditioning fan is not in use, it can prevent external water from entering the interior of the fan casing, and prevent water from entering the interior of the air-conditioning casing after the subsequent blades rotate, causing damage to the internal parts of the air-conditioning casing.

[0019] 2. Through the opening and closing control of the positive sealing plate, the upper sealing plate and the lower sealing plate, air can be taken in from the lower side air inlet in the initial stage, and from the positive air inlet in the normal operation stage. In the high speed stage of the blades, the upper side air inlet can be opened to provide air intake, so that the fan can control the area of ​​the air supply port opening degree according to actual usage requirements.

[0020] 3. Through the setting of the turntable, when the blades are driven by the main shaft to rotate normally, the turntable can rotate synchronously at the same speed, so that the arc-shaped slot plate is subjected to the centrifugal effect of the rotation of the turntable, so that the positive sealing plate is opened under the cooperation of the linkage rod and the balance frame. The opening range of the positive sealing plate relative to the positive air inlet is proportional to the rotation rate of the turntable, which is used to control the opening range of the positive sealing plate through the rotation speed. When the blades rotate at high speed, the push rod can be inserted into the perforation, so that the upper sealing plate can be adjusted relative to the upper side air inlet, so that the upper side air inlet is in an open state.

[0021] 4. Through the setting of the adjustment mechanism and the cleaning mechanism, and by utilizing the rotation control of the adjustment mechanism, the main rod can control the auxiliary rod to swing back and forth left and right, so that the cleaning brush can act on the outer surface of the dustproof net. This is used to solve the problem that the dustproof net is close to the horizontal height of the equipment installation plane, and dust is easily raised during the air intake stage. Dust is easily attached to the surface of the dustproof net, causing dust accumulation and clogging of the air inlet holes on the surface of the dustproof net.

[0022] 5. Through the setting of the reduction gearbox, the wind force generated by the high-speed rotation of the blades is used to rotate the driven impeller. The deceleration effect of the gear set inside the reduction gearbox and the pushing effect of the positive sealing plate are utilized to enable the transmission mechanism to link the rotation of the output shaft and the adjustment mechanism, so that the cleaning brush acts on the outer surface of the dustproof net without providing it with an additional power source, saving unnecessary production capital investment.

[0023] In summary, the present invention overcomes the deficiencies of the prior art. By utilizing centrifugal force, it can instantaneously adjust the opening size of the air inlet end according to the change in air volume demand, and enhances the waterproof and dustproof effects inside the fan, having high social value and application prospects.

Detailed implementation mode

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Example 1: Refer to Figures 1-15 , an air conditioner blower for preventing water ingress, including an air conditioner housing 100, a water collecting tray 200 is provided at the bottom of the air conditioner housing 100, air conditioner blowers 300 are communicated at both ends of the same side of the air conditioner housing 100, and a drive motor 400 for driving the rotation of the internal components of the air conditioner blower 300 is installed on the side of the air conditioner housing 100. A main shaft 1022 connected to the output shaft of the drive motor 400 is rotatably provided on the air conditioner blower 300; The air-conditioning fan 300 includes a fan housing 1 installed on the side of the air-conditioning housing 100. Both ends of the fan housing 1 are provided with air inlet side housings 2. The main shaft 1022 is rotatably arranged inside the fan housing 1. A fixed disk 102 is provided on the main shaft 1022, and blades 1021 are provided on the fixed disk 102. An air outlet 101 is provided on the front of the fan housing 1. A retaining frame 3 is provided on the outer surface of the air inlet side housing 2. A positive air inlet 301 is provided on the front of the retaining frame 3. Upper and lower parts of the outer ring surface of the retaining frame 3 are respectively provided with a side upper air inlet 302 and a side lower air inlet 303. A dust-proof net 9 is provided on the side lower air inlet 303. An air inlet is provided on the side of the air inlet side housing 2. When the main shaft 1022 drives the blades 1021 to rotate, air can enter from the air inlet, and then the air is conveyed to the inside of the air-conditioning housing 100 through the air outlet 101. The function of setting the dust-proof net 9 is that the height position of the side lower air inlet 303 from the plane of the overall installation of the equipment is relatively close, so that when air flows, dust is easily generated and enters the air-conditioning fan 300 from the side lower air inlet 303. Therefore, the dust-proof net 9 is provided to provide a blocking effect on the dust generated at the bottom.

[0029] Specifically, referring to Figure 1 、 Figure 7 and Figure 10 The inner side surface of the air inlet side housing 2 is provided with an orbital ring 21. A turntable 4 linked with the blades 1021 is rotatably arranged on the orbital ring 21. A sliding hole 41 is provided on the turntable 4. A centrifugal linkage mechanism 42 is slidably sleeved in the sliding hole 41. The setting of the orbital ring 21 enables the turntable 4 to rotate relative to the air inlet side housing 2. The rotation of the turntable 4 can be driven by the rotation of the blades 1021 to control the centrifugal opening degree of the centrifugal linkage mechanism 42 depending on the rotation speed of the turntable 4. The opening degree of the centrifugal linkage mechanism 42 is proportional to the rotation speed of the turntable 4. The faster the turntable 4 rotates, the greater the opening degree of the centrifugal linkage mechanism 42.

[0030] Specifically, referring to Figure 1 、 Figure 7 、 Figure 10 、 Figure 12 and Figure 13 , the centrifugal linkage mechanism 42 includes an arc-shaped groove plate 4201. A sliding seat 4202 slidably sleeved with the sliding hole 41 is provided on the side surface of the arc-shaped groove plate 4201. A sleeve rod 4203 is provided on the arc-shaped groove plate 4201. A through rod 4204 movably sleeved with the sleeve rod 4203 is provided on the inner side surface of the turntable 4. A spring B 4205 is connected to the end of the through rod 4204, and the other end of the spring B 4205 is fixedly connected to the inner end surface of the sleeve rod 4203. When the turntable 4 rotates, the arc-shaped groove plate 4201 will move outward relative to the turntable 4 by the centrifugal force of the rotation of the turntable 4, causing the spring B 4205 to generate elastic deformation. The sliding seat 4202 will move inside the sliding hole 41, and the sliding hole 41 provides a guiding and stabilizing effect for its position movement.

[0031] Specifically, referring to Figure 1 , Figure 3 , Figure 5 , Figure 10 and Figure 11 , a dust-proof frame 31 is provided at the bottom outside of the retaining frame 3. A guiding strip hole 311 is opened on the dust-proof frame 31. A positive sealing plate 32 for closing the positive air inlet 301 is provided inside the retaining frame 3. An upper sealing plate 33 for closing the upper side air inlet 302 is provided on the upper part of the inner ring surface of the retaining frame 3. Telescopic rods 322 are provided on both sides of one end of the positive sealing plate 32 located at the side of the lower side air inlet 303. The end of the telescopic rod 322 is connected with a lower sealing plate 34 for closing the lower side air inlet 303. The setting of the dust-proof frame 31 can block dust during the cleaning of the surface of the dust-proof net 9 or when the equipment is initially started, avoiding excessive dust raising range. The opening and closing of the upper sealing plate 33 and the lower sealing plate 34 for the upper side air inlet 302 and the lower side air inlet 303 are controlled through the linkage of the positive sealing plate 32. When the positive sealing plate 32 is at the maximum opening value, the upper sealing plate 33 is in an open state for the upper side air inlet 302. When the positive sealing plate 32 opens the positive air inlet 301, it will gradually push the lower sealing plate 34 to cover the lower side air inlet 303. The continuous opening of the subsequent positive sealing plate 32 will compress the elasticity inside the telescopic rod 322, making the closing of the lower sealing plate 34 for the lower side air inlet 303 tighter.

[0032] Specifically, referring to Figures 12-15 , a linkage rod 321 is provided in the middle of one end of the positive sealing plate 32. The end of the linkage rod 321 is connected with a balance frame 3211 slidably sleeved with the arc-shaped groove plate 4201. With the action of the centrifugal force when the arc-shaped groove plate 4201 rotates on the turntable 4, the turntable 4 and the balance frame 3211 can present a relative rotation state, enabling the balance frame 3211 to move in position inside the arc-shaped groove plate 4201. Actually, the balance frame 3211 is not in a moving state relative to the air inlet side shell 2, and the outward centrifugal movement of the arc-shaped groove plate 4201 will drive the positive sealing plate 32 to move through the balance frame 3211 and the linkage rod 321 to open the positive air inlet 301. As the rotation speed of the turntable 4 increases, the moving opening amplitude of the positive sealing plate 32 for the positive air inlet 301 will also increase. The setting of the balance frame 3211 is to ensure that when there is a gap between the two turntables 4 during movement, the movement of the balance frame 3211 between the continuous turntables 4 will not be affected by the gap between them.

[0033] Specifically, referring to Figure 11, a perforation 331 is provided on the upper sealing plate 33. Thrust rods 3201 inserted into the perforation 331 are provided on both sides at one end of the front sealing plate 32 located at the side upper air inlet 302. A locking plate A3011 is provided on the upper sealing plate 33. The front surface of the retaining frame 3 is provided with the upper sealing plate 33 that is lock-matched with the locking plate A3011. A locking plate B332 locked with the locking plate A3011 by bolts is provided on the upper sealing plate 33. As the front sealing plate 32 moves under the action of centrifugal force, the thrust rods 3201 will be inserted into the interior of the perforation 331. With the gradual insertion of the thrust rods 3201, the upper sealing plate 33 moves relative to the side upper air inlet 302, so as to open the closure of the upper sealing plate 33 for the side upper air inlet 302, thereby increasing the air inlet channel on the upper part of the outer ring surface of the retaining frame 3, and the air intake volume is increased synchronously according to the rotation speed of the blades 1021.

[0034] Specifically, referring to Figure 5 , a backing plate 3301 is provided on the outer surface of the upper sealing plate 33. A spring A3302 connected to the outer ring surface of the retaining frame 3 is provided on the backing plate 3301. When the upper sealing plate 33 moves relative to the side upper air inlet 302, the spring A3302 will generate elastic deformation. After the thrust rods 3201 withdraw from the interior of the perforation 331, the elastic deformation recovery of the spring A3302 will make the upper sealing plate 33 close the side upper air inlet 302 again.

[0035] Embodiment 2: Referring to Figures 1-15 , the difference between this embodiment and Embodiment 1 is that an adjusting mechanism 7 is rotatably provided at the top end of the outer surface of the air inlet side housing 2, and a dust cleaning mechanism 8 is rotatably provided on the outer surface of the air inlet side housing 2. The adjusting mechanism 7 includes a disc frame 701 rotatably connected to the air inlet side housing 2.

A rotating shaft 702 is connected to the axis position on the other side of the disc frame 701. The rotation of the rotating shaft 702 can be provided with an additional power source to make the rotating shaft 702 rotate, thereby driving the disc frame 701 to rotate, so that the dust cleaning mechanism 8 can swing in position under the drive of the disc frame 701 and the linkage pin rod 704.

[0036] Specifically, referring to Figure 1 , Figure 3 and Figure 7 , the dust cleaning mechanism 8 includes a main rod 801 rotatably connected to the air inlet side housing 2. A sub-rod 802 is provided at the bottom end of the main rod 801. A hole for the main shaft 1022 to pass through is provided on the main rod 801 provided on the air inlet side housing 2 on one side of the fan housing 1, and the rotation of the main shaft 1022 will not affect the main rod 801.

[0037] Specifically, referring to Figure 1 and Figure 3, a cleaning brush 803 acting on the outer surface of the dust-proof net 9 is provided at the bottom end of the auxiliary rod 802, and a top frame 804 linked and matched with the adjusting mechanism 7 is provided at the top of the main rod 801. With the reciprocating swing action of the main rod 801, the cleaning brush 803 can clean the dust adhering to the surface of the dust-proof net 9 provided outside the side lower air inlet 303, so that dust will not accumulate in large quantities to cause blockage of the holes in the dust-proof net 9.

[0038] For other structures not described, refer to Embodiment 1.

[0039] Embodiment 3: Refer to Figures 1-15 , the difference between this embodiment and Embodiment 2 is that a reduction gearbox 5 is provided at the top of the fan housing 1. An input shaft 501 and an output shaft 502 are respectively provided at both ends of the reduction gearbox 5. A driven impeller 5011 is connected to the end of the input shaft 501. A synchronization hole 5021 is opened on the bottom surface of the output shaft 502. A gear set is provided inside the reduction gearbox 5 to control the speed difference between the input shaft 501 and the output shaft 502.

[0040] Specifically, refer to Figure 1 、 Figures 7-9 , an extension plate 22 is provided on the inner side surface of the air inlet side housing 2. A transmission mechanism 6 is rotatably provided on the extension plate 22. The transmission mechanism 6 includes a positioning plate 605 connected to the linkage rod 321, and a positioning sleeve 601 rotatably connected to the extension plate 22. A driving bevel gear 602 is connected to the bottom of the positioning sleeve 601. A driven bevel gear 703 meshing and matching with the driving bevel gear 602 is provided at the end of the rotating shaft 702. The rotation of the driving bevel gear 602 will drive the driven bevel gear 703 to rotate, so that the disc frame 701 rotates around the axis of the rotating shaft 702.

[0041] Specifically, refer to Figure 8, a transmission shaft 603 is rotatably provided on the positioning plate 605. The top end of the transmission shaft 603 is slidably sleeved with the positioning sleeve 601 in the up and down direction. A spacer ring 604 is provided on the transmission shaft 603, and a spring C6041 is provided on the spacer ring 604. The top end of the spring C6041 is connected to the bottom surface of the driving bevel gear 602. The movable sleeving mode between the transmission shaft 603 and the positioning sleeve 601 enables the transmission shaft 603 to drive the positioning sleeve 601 to move and rotate, and the transmission shaft 603 can adjust the up and down height position inside the positioning sleeve 601. With the movement of the positive sealing plate 32, the positioning plate 605 can lift the relative height between the transmission shaft 603 and the positioning sleeve 601, so that the synchronous end 6031 is inserted into the synchronous hole 5021, and the synchronous hole 5021 drives the transmission shaft 603 to rotate. By means of the linkage between the positioning sleeve 601 and the transmission shaft 603, the positioning sleeve 601 drives the driving bevel gear 602 to rotate. When the spacer ring 604 is in the state of elastic deformation and compression, the synchronous end 6031 is inserted into the synchronous hole 5021 to make the two rotate synchronously. When the elastic deformation of the spacer ring 604 is restored, the synchronous end 6031 is separated from the synchronous hole 5021, and the two no longer rotate synchronously.

[0042] Specifically, referring to Figure 8 , a synchronous end 6031 is provided at the top end of the positioning sleeve 601, and the synchronous end 6031 is linked and sleeved with the synchronous hole 5021 in a matching manner.
